4 Inch DN80 Stainless Steel Pipeline Basket Strainer Filter
✧ Workflow
The fluid enters from one end into a filter bucket with a certain size of specification, after which the dirt is collected by the filter into the strainers, while the clean filtrate is discharged from the filter outlet. When it is time to clean, simply unscrew the screw plug at the bottom of the main tube, drain the fluid, remove the flange cover, clean and reassemble.

✧ Main filtering role
Removes large particles (coarse filtration), purifies fluids and protects critical equipment (mounted in front of the pump to reduce damage to the pump).
